In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 4100-80-5, name is 3-Methyldihydrofuran-2,5-dione, introducing its new discovery. HPLC of Formula: C5H6O3

3-O-3?(or 2?)-Methylsuccinyl-betulinic acid (MSB) derivatives were separated by using recycle HPLC. The structures of four isomers were assigned by NMR and asymmetric synthesis. 3-O-3?S-Methylsuccinyl-betulinic acid (3?S-MSB, 4) exhibited potent anti-HIV activity with an EC50 value of 0.0087 muM and a TI value of 6.3 × 103, which is comparable to the data for bevirimat (DSB, PA-457), a current clinical trials drug that was also derived from betulinic acid. The anti-HIV potency of 4 was slightly better than that of AZT.

17347-61-4, Name is 2,2-Dimethylsuccinicanhydride, belongs to tetrahydrofurans compound, is a common compound. Application In Synthesis of 2,2-DimethylsuccinicanhydrideIn an article, once mentioned the new application about 17347-61-4.

Two series of lupane-type triterpenoic acid derivatives were synthesized and evaluated for their inhibitory activity against HIV-1 replication in acutely infected H9 cells, based on the fact that betulinic acid (1) and dihydrobetulinic acid (9) were identified as anti-HIV agents. Among the derivatives, 3-O-(3′,3′-dimethylsuccinyl)-betulinic acid (3) and 3-O-(3′,3′-dimethylsuccinyl)-dihydrobetulinic acid (11) both demonstrated extremely potent inhibitory activity with EC50 values of <3.5 x 10-4 muM, and remarkable in vitro therapeutic index (TI) values of 20,000 and 14,000, respectively. 3-O-(3',3'-dimethylglutaryl)-betulinic acid (4) and -dihydrobetulinic acid (12), 3-O-diglycolyl-betulinic acid (5) and -dihydrobetulinic acid (13) and 3-O-glutaryl-betulinic acid (6) were also potent inhibitors of HIV replication with EC50 values ranging from 0.04 to 2.3 x 10-3 muM and TI values from 292 to 2344. In addition, compounds 11 and 12 were also active against HIV replication in a monocyte cell line and in peripheral blood mononuclear cells. Our in vitro assay indicated that these compounds are not inhibitors of HIV-1 reverse transcriptase, whereas they inhibited syncytia formation completely in a concentration range of 20-40 mug/mL. However, 3-O-(2',2'-dimethylsuccinyl)-betulinic acid (2) was also found to be an inhibitor of HIV-induced membrane fusion with an IC100 value of 20 mug/mL, though it displayed significantly lower anti-HIV activity than foregoing compounds with an EC50 value of 2.7 muM and TI of 6.7. Further study is underway to determine the mechanisms of action of these compounds. Do you like my blog? If you like, you can also browse other articles about this kind.

Electrochemical fluorination (ECF) of the ester derivatives of oxolane-2-yl-carboxylic acid (1), oxolane-2-yl-methanol (2) and oxane-2-yl-methanol (3) were investigated. Perfluoro(oxolane-2-yl- carbonylfluoride) (4) was obtained from derivatives of 1 and 2, and perfluoro(oxane-2-yl-carbonylfluoride) (5) was obtained from derivatives of 3 as the desired compounds, respectively. From the ECF of acetates of 2 and 3, perfluorospiroethers having a dioxolane ring were also obtained as the cyclization product in low yield together with the desired perfluoroacid fluoride (4 and 5). The structure of these perfluorospiroethers was confirmed by analyzing the chlorinated products, which were obtained by the reaction with AlCl3.

Screening of the Maybridge compound collection identified 4-arylphthalazinones as micromolar inhibitors of PARP-1 catalytic activity. Subsequent optimisation of both inhibitory activity and metabolic stability led to a novel series of meta-substituted 4-benzyl-2H-phthalazin-1-ones with low nanomolar, cellular activity as PARP-1 inhibitors and promising metabolic stability in vitro.

The identification of novel, non-purine based inhibitors of xanthine oxidase is described. After a high-throughput screening campaign, an NMR based counterscreen was used to distinguish actives, which interact with XO in a reversible manner, from assay artefacts. This approach identified pyrimidone 1 as a reversible and competitive inhibitor with good lead-like properties. A hit to lead campaign gave compound 41, a nanomolar inhibitor of hXO with efficacy in the hyperuricemic rat model after oral dosing.
